IMPROVEMENT IN TURBINE-WHEELS.

The Schedule referred to in these Letters Patent and making part of the same.'

To 'all whom it may concern:

Be it known that I, V. M. BAKER, of Preston, in the county of Fillmore, and State of Minnesota, have invented a new and improved Turbine Water-Wheel; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

`Figure l is a top view of my improved water- Wheel.

Figure 2 is a side view of the same, part being broken away to show the construction.

Figure 3 is a detail horizontal section of the same, taken through the line :t az, g. 2.

Figure 4 is a detail sectional view of the same, taken through the line y y, fig. 3.

Figure 5 is a top view of the box forsupporting the shaft, the top plate being removed.

Figure 6 is a detail sectional view of the same, taken through the line z c, g. 5.

Similar letters of reference indicate corresponding parts.

My invention has for its object to improve the construction of water-wheels, so as to make them more effective and convenient in use, enabling' them to utilize a larger per cent. of the power of the water, and to be more conveniently operated, than when constructed in the ordinary manner.

And it consists in the construction and combinavtion of the various parts, as hereinafter more fully de scribed.

A is the shaft, to which the wheel is attached, the lower end of which revolves in a step, B, and which passes up through the box C, attached to the upper part ofthe cap-plate d* ofthe outer case D.

In the box C are placed two blocks E, the concave faces of which, or ribs formed upon said concave faces, enter a circular groove formed around the shaft A, so that the weight of the shaft and wheel may be partially supported by said blocks and box.

The blocks E are moved up to the shaft A, to compensate for wear, by set-screws F passing in through the sides of the box C, and the forward ends of which rest against the said blocks E, as shown in figs. 5 and 6. v

G is a tube, through which the shaft A passes, and upon the lower end of which is formed, or to it is attached, a liange, g', fitting upon and forming the top plate of the box C. l

H is the wheel, which is made with long buckets hl, and short buckets h2, connected together at the lower ends of thefshort buckets h2.

The long buckets h are made thick at their outer edge, where they connect with the short buckets h2, so that the water may be carried to the lower or curved parts of the buckets h, without loss of power from iction.

The buckets h1, from their points of connection with the short buckets h2, are made upon a true cnr've.

By this construction and arrangement of the buckets h h2, the direct and reacting forces of the water are utilized to a much greater extent than is possible wit water-Wheels otherwise constructed.

D is the outer orstationary case of the wheel, in the upper part of which are formed the chutes I, by which, and the gates J, the wateris conducted to the wheel H. i

The gates J are formed as shown in fig. 3.

The inner plates of the gates J are curved inward at their forward ends, so that as the said gates are hoisted or opened, their forward edges may keep close to the face of the' wheel H, so as to insure the passage of all the water from the chute to the Wheel, thus preventing loss of power from some of the water escaping between the chute and wheel, as it would otherwise be liable to do.

-The outeil plates of the gates J are made curved, as shown in iig. 3, so that the said gates, in connection with the chutes I, may conduct the waterto the wheel with the least possible amount of friction.

The gates J are kept in pro'per position by guidelanges or ways cl2, as shown in iig. 3.

K is a ring-plate, to the centre of the cross-arm of which is'attached a sleeve, k', fitting upon the tube G. Through the plate K are formed slots to receive the upper ends of the levers L, where they are secured in place by the short levers or hooks M, as shown iu figs. l and 2. v

The levers Lare pivoted to supports N, attached to the outer case D, and their lower ends enter sockets j', formed in or Aattached to the gates J, so that the said gates may be opened andl closed by operating the rin g-plate K.

To the lower ends of the levers L are pivoted small wheels, O, to diminish the friction in operating the gates J, as shown in fig. 2.

To one side of the ring-plate K is attached, or upon it is formed, a rack, P,.into the teeth of which mesh the teeth of the small wheel Q attached to the shaft R. rlhe shaft R revolves in bearings attached to the case D, and mot-ion may be given to it, to operate'the gates J, by a crank or other convenient means.

Having thus described my invention,

I claim as new, and desire-to secure by Letters Patentvl.
